okay well this is good news! I would recommend an after market performance rear motor mount, but those can be expensive and can increase the vibration felt in the cabin. However, the engine wont shift around when youre getting on it =). Do not buy an Anchor motor mount, the rubber is as soft as pencil eraser. If you'd like the stock feeling, durability, and quality, then I could only recommend a factory mount https://www.realmazdaparts.com/oem-p...ItM2wtbDQtZ2Fz
unless you are referring to the mount on the transmission side, in that case it would be https://www.realmazdaparts.com/oem-p...ItM2wtbDQtZ2Fz

So you disconnected the harness from the AC compressor and your cut out is gone (and now the AC compressor is not plugged in)? or it was disconnected, now it is connected, and the cut out is gone?

What's the CEL code for?

 

Transmission rear mount.
i bought this because it was $1600. I do alot of weekend traveling. Whether to casino(3hrs) or picking up motorcyes( 3 to 6) hour drives depending where i go.
i have little kids so thats why i wanted a 3rd row.
i just need it for a year of this kinda driving the ill sell it for a new car.
when i bought it replaced all struts shocks brand new tires. Basic tune up on it. After these issues imm be comfortable doing long trips.

i did have time for the car today. Prob over the weekemd.

 

Weird update.. this is just a hunch.
So i got my motor mounts in changed the top by passenger wheel. Took 95% of the rattling, clutch shutter away. Car runs very quiet again. CEL stayed on for an hour or so the turned off. Couple day in all is running as should be. No cut out at WOT. :-)
my thoughts are..... the mount was making a hard enough knock that the sensor was picking it up and retarding the timing causing the cutting out.
I'll be change the other 3 mounts this week hopefully whats left of the bump noise will go away. It is very little.
hopefully it stays off
